Motor-driven valve divides bore magnetic valve from the western 2W160-15 closed types four of moral power, and scope that its is pressure-resistant is in 0-1Mpa；Flow
Meter is from the turbine flowmeter of LWGY-DN4 pulses output, and scope that its is pressure-resistant is in 0-1.6Mpa；Water flow switch selects moral Christopher Eccleston
SLKG water flow switches, be characterized in can low hydraulic pressure start, pressure-resistant scope is in 0-0.6Mpa；It is electromechanical to inhale section during fertile pump is selected
DC50C-2480A submersible type adjustable speed water pumps, its range of flow is in 0-2100L/H.
Its operation principle is：
After main road caliber accesses external water stream, motor-driven valve 1 and motor-driven valve 24 are in opening, flowmeter 1
The flow to be supplied water to outside is monitored, and obtains real-time water-carrying capacity, it is known that the concentration of liquid manure proportioning is water and solution mixing
Ratio together, while current are detected, the suction fertilizer pump 6 of manually opened bypass caliber, according to water-carrying capacity size, adjustment
The scope of fertile pump 6 is inhaled well, is adapted to a certain fertilizer-sucting quantity and is synchronously operated, the fixation that this fertilizer-sucting quantity is matched by pre-determined liquid manure
The water-carrying capacity that ratio is monitored with flowmeter 1 is determined.
Solution flows through water flow switch 5 and mixed into main road caliber with current, and liquid manure is now just completed in caliber
The proportioning of concentration, liquid manure mixed liquor bleeder can carry out irrigation use.The flow of 23 pairs of liquid manure mixed liquors of flowmeter is carried out
Monitoring, obtains real-time liquid manure flow, and it is dense that the real-time water-carrying capacity with reference to measured by flowmeter 1 can obtain actual liquid manure proportioning
Degree, can be using this concentration as feedback signal, as the foundation of the fertile pump 6 of fine setting suction, so as to which whole device forms closed-loop system, with this
Circulation work, realize stabilization, accurately and efficiently liquid manure concentration proportioning.
Embodiment 2
As shown in Fig. 2 a kind of concentration proportioning device irrigated for water-fertilizer integral, including main road caliber and it is installed
On motor-driven valve 1, motor-driven valve 24, flowmeter 1 and flowmeter 23, in addition to bypass caliber and the current that are installed on it
Switch 5 and the fertile pump 6 of suction.Motor-driven valve 1 is connected DC12V power supplys with motor-driven valve 24 and is connected by control circuit with controller, stream
Gauge 1, flowmeter 23 are connected DC5V power supplys with water flow switch 5 and are directly connected with controller I/O mouths, inhale fertile pump 6 and connect
DC24V power supplys are simultaneously connected by control circuit with controller.
Controller is communicated with industry control screen by serial ports from STC15W series monolithics and realizes man-machine interaction, and flowmeter is selected
The resistance to step-by-step counting turbine flowmeter for being pressed in below 1.75Mpa, motor-driven valve select the voltage-controlled spherical motor-driven valves of DC12V, inhale
Fertile pump is regulated and controled from PWM, and range of flow is 0~2400L/H adjustable speed water pump, and automatic water flow switch can from power 90W hydraulic pressure
The HT-60 of tune.
Its operation principle is：
After main road caliber accesses external water stream, controller opens motor-driven valve 1 and motor-driven valve 24, one 2 pairs of flowmeter
The flow that outside is supplied water is monitored, and the suction fertilizer pump 6 of bypass caliber is synchronously carried out with a certain fertilizer-sucting quantity while detecting current
Work, the value for the water-carrying capacity that this fertilizer-sucting quantity is monitored by presetting liquid manure matched proportion density with flowmeter 1 are determined.Solution flows through
Automatic water flow switch 5 is mixed into main road caliber with current, and automatic water flow switch 5 is unidirectional conducting switch, for preventing
The current of main road caliber flow into bypass caliber, and now current simultaneously flow through flowmeter 23 with solution, and 23 pairs of liquid manure of flowmeter mix
Flow quantity is closed to be monitored.Actual matched proportion density can be drawn by the flow detected by flowmeter 23 and flowmeter 1, will
This concentration is sent to as feedback signal inhales the fertile progress of pump 6 real-time monitoring, forms close loop maneuver system, is realized with this circulation work
Stable, accurate liquid manure concentration proportioning.
Wherein, when carrying out liquid manure concentration proportioning, water inlet is accessed into running water pipe, motor-driven valve one is opened by controller
1 and motor-driven valve 24, the flow of water is monitored with reference to flowmeter 1.After obtaining the flow of water, match somebody with somebody according to presetting liquid manure
Specific concentration, carry out the flow of regulation fertilizer in proportion.For example, presetting concentration is 10%, detect that now water-carrying capacity is 20L/min,
So can be according to formula
Fertile flow/(20L/min+ fertilizer flow)=10%；(1)
It is 2.22L/min to obtain fertile flow.The regulation and control of wherein fertile flow can regulate and control variable frequency pump 6 to realize by controller, root
Fertile flow can be regulated and controled in real time according to the situation of change of water-carrying capacity, make the stable certain mistake in presetting concentration of matched proportion density
Within the scope of difference, so as to reach the purpose of liquid manure concentration proportioning.Making the difference comparison by flowmeter 1 and flowmeter 23 can obtain
Go out the liquid manure concentration in actual exit, to carry out contrast verification with presetting concentration：
In the case where closing water inlet valve, PWM regulation and control incrementally are carried out to variable frequency pump, until reaching it most
Untill big speed, flowmeter output signal is gathered simultaneously in PWM control process, so as to draw PWM frequency with inhale fertile flow it
Between relation.In the case of normal water supply, by gathering flowmeter output signal come the flow of monitoring calculation water, according to water
The suction fertilizer flow of fertile pump is inhaled in flow, in proportion control, now inhale the flow of water in fertile flow-rate ratio with inhale fertile flow and ratio
The calculated value of liquid manure matched proportion density as ideally.And rate of discharge is subtracted into inlet flow rate and can obtain fertilizer-sucting quantity, will
Fertilizer-sucting quantity can obtain actual liquid manure matched proportion density compared with exporting total flow.Constantly circulation inhales fertile flow to realize in this way
It is adapted with the flow of water, so as to reach the purpose of accurate proportioning control.The result is as shown in the table.
Test result indicates that：This method can accurately match out target liquid manure concentration according to preset concentration, have higher
Precision, inside and outside water-carrying capacity in a big way change can preferably automatic adaptation fertilizer flow come ensure liquid manure match standard
True property, only when external water stream amount becomes very little, reach 5.0L/min or it is smaller when error can gradually increase.
